Tools Documentation

Clear Free and Pro limits for every major conversion service. Uploads go directly to disk, then Redis and BullMQ route each task to the correct background worker.

Disk uploads

Files are streamed to server disk first, so large uploads are not held in API memory.

Queue workers

Redis and BullMQ send each task to PDF, office, OCR, image, or cleanup workers.

Plan validation

Free and Pro limits are enforced before each job enters the processing queue.
